APPL-14-000025 - The macOS system must display the Standard Mandatory DOD Notice and Consent Banner at the login window.

Information

Displaying a standardized and approved use notification before granting access to the operating system ensures that users are provided with privacy and security notification verbiage that is consistent with applicable federal laws, Executive Orders, directives, policies, regulations, standards, and guidance.

System use notifications are required only for access via logon interfaces with human users and are not required when such human interfaces do not exist.

The policy banner will show if a 'PolicyBanner.rtf' or 'PolicyBanner.rtfd' exists in the '/Library/Security' folder.

The banner must be formatted in accordance with DTM-08-060.

Solution

Configure the macOS system to display a policy banner by creating an RTF file containing the required text. Name the file 'PolicyBanner.rtfd' and place it in '/Library/Security/'.

Update the permissions of the '/Library/Security/PolicyBanner.rtfd' file with the following command:

/usr/bin/sudo /bin/chmod 644 /Library/Security/PolicyBanner.rtfd
